QIn heating operation, defrost operation is performed when TE sensor temperature satisfies any condition in A zone to D zone.

RThe defrost operation is immediately finished if TE sensor temperature has become 12°C or more, or it also is finished when condition of 7°C ≤ TE < 12°C has continued for 1 minute. The defrost operation

is also finished when defrost operation has continued for 10 minutes even if TE sensor temperature has become 7°C or lower.

SAfter defrost operation has finished, the compressor and the outdoor fan start heating operation after stopped for approx. 50 seconds.

* The minimum TE value between 10 and 15 minutes after heating operation has started is stored in memory as TE0.

A zone		Defrost operation is performed in this zone when TE0-TE ≥			3 continued for T seconds.

B zone		Defrost operation is performed in this zone when TE0-TE ≥			3 continued for T seconds.

C zone		Defrost operation is performed when this zone continued for T seconds.

D zone		Defrost operation is performed when this zone continued for T seconds.
